Jun 9 2017 - 11:00 E6 Yukawa couplings as D-instanton effects Andres Collinucci One of the main motivations for using F-theory as a model building tool is the fact that it can naturally generate a 10 10 5 Yukawa coupling, by engineering a so-called E6-singularity. Seminar
Jun 12 2017 - 15:00 Microscopic model of quantum butterfly effect: out-of-time-order correlators and traveling combustion waves Lara Faoro In a chaotic classical system a small perturbation leads to the exponential divergence of trajectories characterized by Lyapunov time. Seminar
Jun 26 2017 - 15:00 Exorcising the Ostrogradsky ghost: Construction of healthy higher-derivative theories Hayato Motohashi Scalar-tensor theories serve models for inflation and dark energy. Seminar
Jun 29 2017 - 15:00 Nucleon structure from 2+1-flavor dynamical Domain-Wall Fermion ensembles Shigemi Ohta I will discuss lattice-QCD numerical calculations of nucleon structures using 2+1-flavor dynamical domain-wall fermion (DWF) ensembles jointly generated by RIKEN-BNL-Columbia (RBC) and UKQCD collab Seminar
Jul 3 2017 - 15:00 Neutron Stars and Gravitational Wave Observation of Strong-field Gravity Alvaro de la Cruz-Dombriz In the context of scalar-tensor gravity theories, the apparent mass of neutron stars as seen from an observer at infinity is numerically calculable but requires careful matching, first at the star Seminar
Jul 10 2017 - 15:00 Freeze-in dark matter and its phenomenological potential Bryan Zaldivar Freeze-in mechanism for dark matter (DM) production is lately gaining a lot of popularity because of 1) lack of WIMP evidence, and 2) the possibility to probe it at experiments may not be at all ho Seminar
Jul 13 2017 - 15:00 Novel features of large-N limits: decoherence, entanglement and area operators in AdS/CFT. Javier Magan Most candidates to quantum gravity theories are "large-N" models. Seminar
Sep 18 2017 - 15:00 Black Hole Microstates and the Information Paradox Iosif Bena Einstein’s General Relativity applied to black holes appears to lead to Information loss, thus violating one of the fundamental tenets of Quantum Mechanics. Seminar
